All good points...for factory rockers. Holes toward exhaust for stamped steel arms.
The PRWs the OP is using don't care where the holes are pointing..oil will get out to the necessary areas either way.
(The shafts PRW and others supply with their kits have holes on center with the mounting holes)..
Joel, a good pre-install thing to do is run something like a small piece of wire through each oiling hole. PRW has been known to leave metal/gunk in them, and even forget to drill the occasional hole. I'd remove and clean each adjuster and the rocker threads as well..
